ROTARY DOOR FOR COLD-STORAGE ROOMS.

SPECIFICATION forming part of Letters Patent N 0. 779,209, dated January 3, 1905. Application filed May 20, 1904. Serial No. 208,841.

To all whom, it may concern:

Be it known that 1, JOHN F. DRUOKER, a citizen of the United States, residing in New York, borough of Manhattan, in the State of New York, have invented certain new and useful Improvements in Rotary Doors for Cold-Storage Rooms, of which the following is a specification.

This invention relates to an improved rotary door for cold-storage rooms in which liquids or other articles are stored in barrels, so as to permit the convenient removal of the barrels from the cold-storage without increasing the temperature in the cellars or other rooms in which they are stored, the door being especially adapted for the storage rooms or cellars of breweries; and the invention consists of a rotary door for cold-storage rooms, comprising a horizontal casing supported by upright side walls in the delivery-openings of the cold-storage rooms, said casing being provided at either end with openings for the barrels or other packages, radial partitions attached to a central shaft supported in bearings of the end walls, means for arresting the rotary motion of the radial partitions located at the outgoing end of the door-casing by the outgoing barrel, and means for holding the barrels at the ingoing end while a barrel is delivered at the outgoing end of the rotary door.

The accompanying drawing illustrates a side elevation of my improved rotary door for cold-storage rooms, showing two barrels at the ingoing end and one barrel at the outgoing end of the casing.

Referring to the drawing, A designates the cement floor of a storage-wareroom, which is is preferably provided with rails f, so that the barrels or other articles can be readily moved over the same. At the ingoing and outgoing ends of the casing A are arranged openings F of sufficient size to permit the rolling in and out of the barrels B. Journaled in the casing A is a horizontal shaft S, carrying radial partitions P, which are reinforced by ribs and provided at the ends and sides with elastic packing-strips so as to cause the tight'closing and fitting of the partitions to the upright end walls or heads B of the casing and to the arc-shaped portion 6 of the floor A, so that during the rotation of said partitions the cold air in the warehouse-room cannot pass to the outside nor the warmer outside air pass to the inside of the cold-storage room. To the shaft S is keyed a ratchet R, having as many teeth as there are partitions, while a check-pawl R, pivoted to the head of the casing, engages the ratchet and permits the partitions to be moved only in an ingoing direction.

The ingoing and outgoing ends of the cement floor are slightly inclined, so that the barrels roll by gravity through the ingoing end of the casing A into the compartments formed by radial partitions, then rotate the partitions by gravity, and deliver the barrels at the outgoing end of the casing. It has been found advisable to so regulate the speed at which the barrels are delivered to the door that they enter every other compartment.

At the ingoing end of the floor are arranged stop-levers f, which are fulcrumed to the floor and raised by the weight of the barrel passing over the shorter end f of the same above the cement floor at the ingoing end, so that the longer end f 3 arrests the next barrel and holds it in position until the first barrel is fully delivered into its compartment. As soon as this is accomplished and the shorter end f of the fulcrumed stop-lever is released by the barrel the weight of the barrel will act on the radial partition against which it rests, rotate the door, and move along the cement floor and out of the casing at the delivery end of the same. As soon as the stop-lever f is released the next barrel is then moved forward into the space ready to be delivered by the next forward motion of the door, and so on, while simultaneously the barrels are delivered at the other end of the rotary door.

To permit the outgoing barrel to move freely over the floor without being followed too closely by the barrels in the next following compartments between the radial partitions, a stop-lever g is arranged at the outgoing end of the casing in such a manner that its inner end is heavier than the outer end, so that when the weight of the barrel acts on the shorter end g its longer and heavier end g is raised into a suitable recess in the reinforcing-ribs of the partition-walls, so as to arrest for a short time the rotary motion of the partitions, as shown in the drawing, and permit thereby the barrel to clear the shorter end of the stop-lever 9', so that the weighted stoplever is dropped into the space in the cement floor provided therefor and permits the rotation of the partitions under the pressure of the next following barrels. In this manner the barrels are delivered successively from the interior of the rooms to the outside of the same without any raising of temperature or loss of cold, which forms at present a very objectionable feature at the delivery end of cellars of breweries,cold-storage warehouses,&c.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a barrel-delivering door for cold-storage rooms,the combination, with a casing having openings at the ingoing and outgoing ends, of a plurality of, radial partitions rotatable in said casing, and means operable by the outgoing barrels for intermittently locking said partitions against movement.

2. In a barrel-delivering door for cold-storage rooms, the combination, with a casing having openings at the ingoing and outgoing ends, of a plurality of radial partitions rotatable in said casing, means operable by the ingoing barrel for temporarily arresting the following barrel, and means operable by the outgoing barrel for temporarily arresting the movement of said partitions.

3. In a barrel-delivering door for cold-storage rooms, a casing provided with openings at the ingoing and outgoing ends, a plurality of radial partitions rotatable in said casing, and a fulcrumed stop-lever operable by the outgoing barrel for intermittently locking said partitions against movement.

4:. In a barrel-delivering door for cold-storage rooms,the combination,with a casing having openings at the ingoing and outgoing ends, of a plurality of radial partitions rotatable in said casing, and a stop-lever in proximity to the outgoing end of said casing, said stop-lever being operable by the outgoing barrel to abut against one of said partitions for temporarily arresting the movement of all of the same.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.

JOHN F. DRUCKER.
